Here’s an example of a global warming consequence that wasn’t exactly on my radar, and some strange news from our neighbors to the north.

The Canadian navy has traditionally had a good relationship with the garbage on board its ships: the cold Arctic temperatures have kept the mess frozen, allowing refuse and olfactory senses to live harmoniously.

Then came global warming. The increased temperatures have caused quite the stink on Canadian naval ships, so much so that the navy is relaxing regulations and allowing ships to dump the garbage and even raw sewage at sea. A portion of an internal navy memo was reprinted by The Canadian Press:

The changes ‘help alleviate our COs (commanding officers’) concerns (with regard to) accumulated food remnants stored in garbage bags on decks during ever-increasing global warming summers…These food remnants may decay or putrefy and generate an occupational health and safety issue on board ships (that) our COs can ill afford while striving to enforce Canadian sovereignty in our internal Arctic waters."

The orders – part of the more relaxed provisions in the Arctic Water Pollution Prevention Act – allow for dumping if there are "operational" or safety reasons, or if capacity is exceeded.

These provisions, and the increased number of ships being sent north on sovereignty patrols, have many people arguing that taking the smelly garbage to a port for unloading is the worth the inconvenience, especially when the alternative is dumping it at sea.

However, navy officials say dumping would be worst-case-scenario, and that navy ships are still much more restrictive in their environmental stewardship than the law requires them to be.
